Baakadaha cuntadawaa cabbir muhiim ah oo lagu hubinayo in gaadiidka, iibinta iyo isticmaalka badeecadaha aysan waxyeello u geysan xaaladaha deegaanka ee dibadda iyo si kor loogu qaado qiimaha badeecadaha.Iyadoo ay kor u kacday tayada nolosha ee dadka deegaanka, saamaynta walxaha ay ku leeyihiin nolol maalmeedka dadka deegaanka ayaa sii kordhaysa, iyo dhibaatada wasakhowga cadaanka ahi waa mid aad iyo aad uga sii daran.Maaddooyinka polymer-ka ee noolaha ah waxay noqdeen meel kulul xagga cilmi-baarista iyo horumarinta agabka baakadaha cuntada.Walxaha polymer-ka noolaha ahUma baahnid deegaan gaar ah ama xaalado dibadeed oo taxane ah sida iftiinka, kulaylka iyo biyaha habka xaalufka.Kaliya waxay u baahan yihiin inay isticmaalaan microorganisms si ay u soo saaraan fal-celin kiimiko kiimikaad oo wanaagsan oo ugu dambayntii ay soo saaraan kaarboon laba ogsaydh.Dhammaan noocyada maaddooyinka ay soo saarto falcelinta nabaad-guurku ma soo saari doonaan wax wasakh ah oo khatar yar uma keenayaan caafimaadka aadanaha.
noolayn karaQalabka polymer uma baahna deegaan gaar ah ama xaalado dibadeed oo taxane ah sida iftiinka, kulaylka iyo biyaha habka xaalufka.Kaliya waxay u baahan yihiin inay isticmaalaanmicroorganismssi loo soo saaro falcelin physicochemical wanaagsan oo ugu dambeyntii dhalisocarbon dioxide.Dhammaan noocyada maaddooyinka ay soo saarto falcelinta nabaad-guurku ma soo saari doonaan wax wasakh ah oo khatar yar uma keenayaan caafimaadka aadanaha.
Bacaha baakadaha noole rogrogmi kara -bacaha kafeegaiyo bacaha dib loo warshadayn karo -bacaha cuntadaWaxaa soo saaray Yantai Meifeng Plastic Packaging Co.
Waxaa jira saddex nooc oo waaweyn oo ahnoolayn karoalaabta polymer.Mid ka mid ah waa maadooyinka polymer-ka ee ay soo saaraan noolaha, kuwaas oo inta badan laga helo halsano microbial, iyo wakiilka ugu badan waa polyhydroxybutyrate, kaas oo leh sifooyin biodegradation wanaagsan.Si kastaba ha ahaatee, wax-soo-saarka iyo kharashyada wax-soo-saarka alaabtan ayaa ah kuwo aad u sarreeya, marar dhif ahna loo isticmaalo wax-soo-saarka gaarka ah.Midda labaad waa walxaha polymer synthetic.Waqtigan xaadirka ah, alaabada polymer synthetic ee inta badan loo isticmaalo suuqa Shiinaha waa aalkolada polyvinyl iyo polycaprolactone.Waxaa ka mid ah, polycaprolactone si ballaaran ayaa loogu isticmaalaa baakadaha cuntada.Midda saddexaad waa walxaha polymer-ka dabiiciga ah.Maaddooyinka polymer-ka caadiga ah ee dabiiciga ah waxaa ka mid ah cellulose, istaarij, borotiin, iyo chitosan sida qalabka matrixka.Ka dib markii la isticmaalo muddo wakhti ah, alaabta polymer-ka dabiiciga ah si fiican ayaa loo dhimi karaa oo aan wax saameyn ah ku yeelan deegaanka deegaanka dibadda.wasakh kasta.
noolayn karapolymers waa mid ka mid ah qalabka ugu cusub ee goobta baakadaha.polymers biodegradable waxay leeyihiin faa'iidooyinkailo ballaaran, dib u warshadayn, ilaalinta deegaanka iyo wasakh la'aan,laakiin bioopolymers-yadu waxay leeyihiin xaddidaadyo gaar ah marka la eego iska caabbinta kulaylka, ogsijiinta iyo guryaha uumiga uumiga biyaha, qiimaha iyo sifooyinka farsamada.Sidaa darteed, cilmi-baarista alaabtan baakadaha waxay u baahan tahay in la sii qoto dheereeyo si loo hagaajiyo nolosha shelf, qiimaha nafaqada iyo badbaadada microbial ee cuntada.
Natiijo ahaan, shirkado badan oo badan ayaa bilaabay inay horumariyaan baakadaha ka samaysan walxaha noolaha, iyagoo la socda isbeddelka waqtiyada iyo la qabsiga suuqyo cusub.
